Chris402, I know basically everyone has already said this, but its just not worth injecting oxy. I'm speaking from experience. I know its boring, but if you want the full benefit of the pill, just take it orally. When you crush up the pill to inject it, you leave so much of the medicine behind in the spoon, its a HUGE waste. And then there's all the health aspects, just as everyone has mentioned. Also, in my experience, there's no real rush from injecting oxy. Truth is, I don't really feel much of anything from it.
What is your reason for wanting to inject it? If its to have the effects hit you faster, then I would suggest snorting it. By snorting it, you avoid 1st pass metabolism by the stomach and liver. Instead, the drug is absorbed through the membranes of your sinuses and goes directly into your blood stream (which is what injecting does anyway). If you're looking to experience the full effect of the pill, then I suggest just taking it orally. That way none of the medicine is lost or gone to waste.
Hope this was helpful.
